Diro builds document design and automation software that turns form responses and structured data into print-quality PDF documents. Teams design a template once in a visual, block-based editor, connect data sources like Typeform, Tally, Google Forms, or CSV imports, and automatically generate certificates, invoices, reports, and assessments at scale. A REST API lets developers embed document generation into their own products and workflows. Diro offers a free plan, with paid plans for higher volumes and API access.
